9 The Two-Pipe Solution Arctic National Wildlife Reserve Yukon Flats Wildlife Reserve Ivvavik National Park Prudhoe Bay Mackenzie Delta Alaska Yukon Northwest Territories Nunavut Manitoba Saskatchewan Alberta British Columbia WASHINGTON IDAHO MONTANA Inuvik NORTH DAKOTA Mackenzie Valley shortest, least cost for Delta gas Alaska Highway quickest, least cost for Alaska North Slope Gas Environmentally and technically superior Least cost, lowest risk solution

10 Alaska Highway Gas Pipeline Project 2820 km, 42” diameter Operating pressure: 2050 psi Initial volumes: 2.5 Bcf/d Ultimate volumes: 4.0 Bcf/d Initial cost: US$7.6 billion Ultimate cost: US$9.7 billion 2 Year construction Estimated Toll: ~US $1/mcf Arctic National Wildlife Reserve Yukon Flats Wildlife Reserve Ivvavik National Park Prudhoe Bay Mackenzie Delta Alaska Yukon Northwest Territories Nunavut Manitoba Saskatchewan Alberta British Columbia WASHINGTON IDAHO MONTANA Gordondale NORTH DAKOTA Anchorage Whitehorse Prebuild

11 Mackenzie Valley Pipeline Lowest Cost, Quickest to Market for Delta Gas Route Description 1220 km, 30” diameter Operating Pressure 2050 psi Initial Volumes 0.8 Bcf/d Ultimate Volumes 1.2 Bcf/d Initial Cost US $2.0 billion 2 Year Construction Arctic National Wildlife Reserve Yukon Flats Wildlife Reserve Ivvavik National Park Mackenzie Delta Alaska Yukon Northwest Territories Nunavut Manitoba Saskatchewan Alberta British Columbia WASHINGTON IDAHO MONTANA Inuvik NORTH DAKOTA

12 The Mackenzie Valley...a priority for TransCanada A stand-alone Mackenzie Valley Pipeline is a strategic priority for TransCanada It is the closest, least costly project to access incremental gas supply It is a good fit with TransCanada’s existing facilities

13 Route Considerations General route based on historical data Route refinement will consider: aboriginal issues -- traditional knowledge environmentally sensitive areas existing utility corridors presence of permafrost, ice content stability of permafrost slopes frost heave & thaw settlement potential drainage and erosion

14 Construction Issues year winter construction plus 1 year prior for logistics (barging in equipment in summer) River crossings -- 4 major rivers greater than 275 m in width Continuous permafrost and discontinuous permafrost manage with combination of route location, thickness of pipe and temperature of gas

15 TransCanada is Uniquely Positioned Extensive system south of 60 Alberta System can be economically ‘right- sized’ to accommodate Delta volumes Efficient use of existing facilities Lowest overall transportation cost to market Arctic National Wildlife Reserve Yukon Flats Wildlife Reserve Ivvavik National Park Mackenzie Delta Alaska Yukon Northwest Territories Nunavut Manitoba Saskatchewan Alberta British Columbia WASHINGTON IDAHO MONTANA Inuvik NORTH DAKOTA

16 What TransCanada Offers Extensive experience in large pipe construction and natural gas operation in extremely cold weather Successful project management expertise Lowest cost alternative

17 Conclusions Gas from both Northern basins will be required to meet growing demand Each basin will be developed when appropriate for that area Producers currently studying feasibility of pipelines out of each area TransCanada is uniquely positioned to play a key role in getting Northern natural gas to the growing North American marketplace We will work with all stakeholders to help develop the best options for safe, reliable delivery of natural gas
